The cheapest gas to be found was in Asotin County, in the most southeastern corner of the state, where the average price was $4.07.

Only California and Hawaii have higher prices than WA state.  The steady climb began after the state's carbon tax laws went into effect, resulting in steady hikes pretty much over the last 17 weeks.
